COULOMB'S LAW  Coulomb's law is an equation that describes the elecrostatic force between electric charges. Coulomb's law states that the electrical force between two charged objects relative to the product of the quantity of the charge on the objects and oppositely comparative to the square of the distance between the two objects. This physics law was discovered and developed by French physicist Charles Augustin de Coulomb. The discovery was of great importance when the theory of electromagnetism was developed.

-Diagram describing the basic mechanism of Coulomb's law; like charges repel each other and opposite charges attract each other.

FORMULA (EQUATION) ::

**d** -represents the distance between the two objects (** Q1 ** and ** Q2 **) (unit is Meters)
 * Q1 ** - represents the quantity of charge on object one (unit is Coulombs)
 * Q2 ** -represents the quantity of charge on object two (unit is Coulombs)
 * k ** -is constant known as the Coulomb's law constant. If the medium is air the the value is 9.0 x 109 N • m2 / C2 . In the Coulomb's Law equation the units on charge (Coulombs) and the units on distance (meters) will be canceled by the units of ** k **, leaving a Newton as the unit of force.

EXAMPLE :: Suppose that two charges, each with a charge of +1.00 Coulomb are separated by a distance of 1.00 meter. Determine the magnitude of the electrical force of repulsion between them.

SOLVING THE EQUATION :: **Given:**
 * The first step to solving the problem is listing the information already provided.

Q1 = 1.00 C Q2 = 1.00 C d = 1.00 m

Coulomb's Law formula. After the values are substituted the rest is using basic algebra to solve the problem.
 * After identifying what is already given the second step is to substitute the known values into the

Felect = k • Q1 • Q2 / d2 Felect = ( 9.0 x 109 N•m2/C2 ) • (1.00 C) • (1.00 C) / (1.00 m)2 **Felect = 9.0 x 109 N**

Coulomb laws were discovered by th Charels Coulomb in eighteenth century.It has to #|deal with the how force varies with a distance between 2 objects or F = K((Q1xQ2)/D2). Units of charge for this law are called coulombs and abbreviated as C. It turns out that chrage of 1 C is a chrage of 6.25billion of billions electrons. Seems like alot but really this charge passes only through 100W light bulp for a little over than a second.

Coulumbs law is like moles in a way because they both have constant values and they are both used to measure. 1 Coulomb = 6.25x10^18e-
 * Coulombs Law **

When two particles are charged, an electric force is created. The larger the charges the larger the forces as shown in the graph. Those are the ideas that help understand along with knowing that opposite charges attract and same repel. The formula that measures the forces is this...**F=kq1q2/d2**

If the quantity of charge of either the nucleus or the surrounding electrons were greater, the force between the nucleus and the electron would be greater

If the distance between the nucleus and electron were greater, the force would be less

Coulombs law is simular to Newtons universal law of gravitation ** (Fg =Gm1m2/d2) **. This is because both are inverse square laws, both have a constant value (k,G), both depend on fundamental property (mass, charge). The only difference is that the electric force can be either attractive or repulsive, while gravitational force can only be attracted
